Harlow was built for the woman who spent years being told her symptoms were normal, her labs were fine, and she just needed to "manage stress better."
Started in San Francisco by a team of clinicians and engineers who knew women's health was being systematically underserved.
Dr. Nadia Hossain, Founder & Chief Medical Officer
"She spent eight years visiting doctors who told her everything was fine. It wasn't."
Harlow was founded after our CMO, Dr. Nadia Hossain, watched her sister spend eight years cycling through doctors, endocrinologists, gynecologists, and GPs, each reviewing the same standard labs and sending her home with the same answer: everything looks normal.
It wasn't normal. A single expanded hormone panel eventually revealed low progesterone, subclinical hypothyroidism, and a cortisol pattern consistent with adrenal fatigue. Three treatable conditions. Eight years of being dismissed.
of women report being dismissed by a doctor when presenting hormonal symptoms for the first time. Most wait over 4 years for a correct diagnosis.
That experience became Harlow's founding question: what if every woman had access to a clinician who actually listened, combined with the lab data to back it up? We've spent three years building the answer.
Today, Harlow serves 40,000+ members across the US. We've helped women understand PCOS, perimenopause, thyroid dysfunction, fertility challenges, and the hormonal root causes of skin, sleep, and mood issues that most practices still treat in isolation.
We're not trying to replace your doctor. We're trying to be the thing that should have existed all along.
We don't guess. We test. Every treatment plan at Harlow starts with a comprehensive hormone panel because symptoms alone aren't enough to build a real picture of what's happening in your body.
We match every member to a dedicated clinician who knows their full history. No rotating staff, no starting over. The relationship is the product.
We tell members what's actually in their labs, what it means, and what can be done in plain language. No jargon, no vague reassurance, no softening results to avoid difficult conversations.
Quality hormonal care has historically been available only to women who could afford expensive private specialists. We're changing that without cutting corners on clinical standards.
Every Harlow clinician has advanced training in hormonal and reproductive health. No general practice, no rushed appointments, no dismissive answers. They chose this specialty because they know how long women wait for real care.
We're a team of clinicians, engineers, and designers who believe women's health has been underbuilt for too long. If that bothers you, too, we'd like to talk.
We're distributed across 12 cities. The clinical team is fully remote, and the engineering team is hybrid. We build asynchronously and meet with intention.
Product decisions run through our medical team first. Always. Built for safety and outcomes.
Every team member and their family get a full Harlow membership on us.
